FIELD OF THE INVENTION

The present invention relates to a wrist brace for immobilizing and protecting a patient's forearm, wrist, and hand.

BACKGROUND

Immobilizing a patient's forearm, wrist, and hand can promote healing of bone fractures and soft-tissue injuries (e.g., sprains), and so wrist braces and supports are often used for this purpose. Conventional wrist braces are designed to fit the typical patient with somewhat frustoconical forearms, whereby the arm tapers from the elbow to the wrist (i.e., narrower near the wrist and wider near the elbow). For patients with arm shapes that deviate from standard—especially obese patients or patients with muscular forearms—conventional wrist braces can provide a poor fit. If a patient with non-standard forearms tries to manipulate a conventional wrist brace to apply uniform pressure to the patient's forearm and wrist, straps for securing the wrist brace can wrap helically along—rather than circumferentially around—the patient's forearm, rendering ineffective the mechanism for securing the wrist brace to the patient. For example, hook-and-loop fasteners can become misaligned and thus ineffectual.

SUMMARY

The present wrist brace includes an advantageous lacing configuration that provides a cast-like compression on a patient's forearm, wrist, and hand to restrict flexion, extension, and lateral movement of the wrist joint. By pulling an improved lacing mechanism, tension in a lace equilibrates along the length of the wrist brace in a way that applies consistent compression to the patient's forearm and wrist.

Exemplary wrist braces (e.g., wrist-brace splints) include a support sleeve (e.g., a U-shaped support sleeve) and a connecting panel (e.g., a stretchable radius panel or a stretchable ulnar panel) that together form a closed wrist-brace sleeve, which is securely positioned around a patient's forearm. A tensioning strap, which extends from the support sleeve, is positioned between a patient's thumb and forefinger and is releasably secured to the closed wrist-brace sleeve. A lace is threaded through openings (e.g., eyelets) or other lace-redirection mechanisms positioned along the edges of the support sleeve and on a lacing closure tab. Regardless of the shape and girth of the patient's forearm, pulling the lacing closure tab circumferentially around the closed wrist-brace sleeve and thereupon releasably securing the lacing closure tab to the closed wrist-brace sleeve achieves a cast-like compression of the wrist brace to the patient's forearm and wrist.

In an exemplary wrist-brace embodiment, the wrist brace includes a U-shaped support sleeve having a dorsal section, a palmar section, and an ulnar section positioned between the dorsal section and the palmar section. The U-shaped support sleeve may be formed from flexible, low-stretch material to help stabilize the patient's forearm, wrist, and hand. Dorsal lace-redirection mechanisms (e.g., dorsal eyelets) are positioned at or near the U-shaped support sleeve's dorsal section, and palmar lace-redirection mechanisms (e.g., palmar eyelets) are positioned at or near the U-shaped support sleeve's palmar section. A radius panel, which is typically stretchable and/or elastic, is secured to the U-shaped support sleeve's dorsal section and the U-shaped support sleeve's palmar section so that together the U-shaped support sleeve and the radius panel form a closed wrist-brace sleeve. The wrist brace further includes at least one lacing closure tab having one or more closure-tab lace-redirection mechanisms (e.g., closure-tab eyelets). A lace, which has a first end fixed to the U-shaped support sleeve nearer the U-shaped support sleeve's proximal end and a second end fixed to the U-shaped support sleeve nearer the U-shaped support sleeve's distal end, is freely threaded though the respective dorsal lace-redirection mechanisms, palmar lace-redirection mechanisms, and closure-tab lace-redirection mechanisms. This exemplary wrist-brace may include an oblique palmar-tensioning strap that extends from the distal end of the U-shaped support sleeve's palmar section. The oblique palmar-tensioning strap is positioned between a patient's thumb and forefinger and is releasably affixed to the U-shaped support sleeve when the wrist brace is secured to the patient's wrist and forearm.

In another exemplary wrist-brace embodiment, the wrist brace includes a U-shaped support sleeve having a dorsal section, a palmar section, and a radius section positioned between the dorsal section and the palmar section. The U-shaped support sleeve may be formed from flexible, low-stretch material to help stabilize the patient's forearm, wrist, and hand. Dorsal lace-redirection mechanisms (e.g., dorsal eyelets) are positioned at or near the U-shaped support sleeve's dorsal section, and palmar lace-redirection mechanisms (e.g., palmar eyelets) are positioned at or near the U-shaped support sleeve's palmar section. An ulnar panel, which is typically stretchable and/or elastic, is secured to the U-shaped support sleeve's dorsal section and the U-shaped support sleeve's palmar section so that together the U-shaped support sleeve and the ulnar panel form a closed wrist-brace sleeve. The wrist brace further includes at least one lacing closure tab having one or more closure-tab lace-redirection mechanisms (e.g., closure-tab eyelets). A lace, which has a first end fixed to the U-shaped support sleeve nearer the U-shaped support sleeve's proximal end and a second end fixed to the U-shaped support sleeve nearer the U-shaped support sleeve's distal end, is freely threaded though the respective dorsal lace-redirection mechanisms, palmar lace-redirection mechanisms, and closure-tab lace-redirection mechanisms. This exemplary wrist-brace may include a thumb-tensioning strap that extends from the distal end of the U-shaped support sleeve's radius section. The thumb-tensioning strap is positioned between a patient's thumb and forefinger, wrapped around the patient's thumb, and then securely and releasably affixed to the U-shaped support sleeve when the wrist brace is secured to the patient's wrist and forearm.

The foregoing illustrative summary, as well as other exemplary objectives and/or advantages of the invention, and the manner in which the same are accomplished, are further explained within the following detailed description and its accompanying drawings and photographs.

DETAILED DESCRIPTION

The present wrist braces with improved lacing are described herein with reference to the accompanying drawings, which depict exemplary wrist-brace embodiments that should not be construed as limiting the scope of the invention. Rather, the exemplary wrist-brace embodiments are provided so this disclosure will be thorough and complete to convey to those having ordinary skill in the art the scope of the invention. In the accompanying drawings, like numbers refer to like elements.

As described herein, the terms “interior surface” and “inner surface” refer to a planar side closest to the patient's hand, and the terms “exterior surface” and “outer surface” refer to a planar side farthest from the patient's hand (i.e., an outer surface is opposite an inner surface).

The term “section” refers in context to a portion or an area of the wrist-brace sleeve. The term “dorsal” refers to the topside of the wrist brace or hand. The term “palmar” refers to the underside of the wrist brace or hand (i.e., the palm). The term “radius” refers to the inner side of the wrist brace, hand, and/or wrist (i.e., the thumb side of the forearm). The term “ulnar” refers to the outer side of the wrist brace, hand, and/or wrist (i.e., the side of the forearm opposite the thumb). The term “proximal” refers to the part of the wrist brace or hand that is closer to the patient's elbow, and the term “distal” refers to the part of the wrist brace or hand farther from the patient's elbow.

The terms “positioned” or “positioning” are used conventionally to embrace one element being fixed or releasably secured to another element. For example, a first element may be positioned against a second element (or positioned between second and third elements) by sewing, by hook-and-loop fasteners, or by other known mechanisms for physically attaching physical elements to each other. The terms “fixed,” “affixed,” and “secured” may include sewn, made integral with, adhered with adhesive, or bonded (e.g., fused with heat).

The terms “freely threaded” and “freely interlaced” are used herein in accordance with the wrist-brace embodiments depicted in FIGS. 1-12 to refer to a lace that is moveably connected to a lace-redirection mechanism, such as an eyelet, rather than fixedly attached to a lace-redirection mechanism. For example, as described herein, a lace that is “freely threaded” through a closure-tab lace-redirection mechanism, which is positioned on or otherwise formed through a lacing closure tab, can facilitate movement of the lacing closure tab along the lace.

FIGS. 1-4 depict an exemplary wrist-brace embodiment sized for a patient. FIGS. 5-6 depict a similar, but longer, exemplary wrist-brace embodiment sized for a patient. Each wrist brace is configured for either a left forearm, wrist, and hand or a right forearm, wrist, and hand. Those having ordinary skill in the art will understand that a left-hand orientation is a mirror image of a right-hand orientation. FIGS. 1-6 illustrate a right-hand orientation. Appendix I includes photographs of an exemplary prototype of the wrist brace depicted in FIGS. 1-4, and Appendix II includes photographs of an exemplary prototype of the longer wrist brace depicted in FIGS. 5-6. The description of the shorter wrist-brace embodiment depicted in FIGS. 1-4 typically applies to the longer wrist-brace embodiment depicted in FIGS. 5-6, except as noted in the supporting description, figures, and photographs.

With reference to the exemplary wrist brace 10 depicted in FIGS. 1-4 (and, as noted, the related, longer exemplary wrist brace 10′ depicted in FIGS. 5-6), the wrist brace 10 includes a closed wrist-brace sleeve 12 defining an interior surface and an exterior surface. The closed wrist-brace sleeve 12 is formed by a stretchable radius panel 14 connected to a U-shaped support sleeve 20, which might also be considered a C-shaped support sleeve.

The U-shaped support sleeve 20 includes a topside dorsal section 22, an ulnar section 24, and an underside palmar section 26. The ulnar section 24 is contiguously positioned between the dorsal section 22 and the palmar section 26 to define the U-shaped support sleeve 20. The topside dorsal section 22 is positioned opposite the underside palmar section 26, and the ulnar section 24 is positioned opposite the stretchable radius panel 14. Typically, the U-shaped support sleeve 20, which opens to a patient's forearm radius, is substantially inelastic (e.g., formed from flexible, low-stretch material) to help stabilize the patient's wrist and hand.

As used herein, the term “elastic” generally refers to material that can be readily stretched or expanded, and then can return to its initial shape (i.e., elastic materials resist deformation by stretching), and the term “inelastic” generally refers to material that resists stretching and elongation. The U-shaped support sleeve 20 may be constructed of lightweight suede-like polymeric materials or other lightweight fabrics (e.g., nylon or PVC) having excellent strength and durability. The interior surface of the U-shaped support sleeve 20 may be enhanced with nonwoven polymeric materials (e.g., nonwoven polyolefins), such as felt fabric, to provide cushioning and support.

The stretchable radius panel 14, which may be cushioned for the patient's comfort, is affixed to both the U-shaped support sleeve's dorsal section 22 and the U-shaped support sleeve's palmar section 26, thereby closing the gap in the U-shaped support sleeve 20 to form the closed wrist-brace sleeve 12. In addition, the stretchable radius panel 14 is typically positioned within the gap in the U-shaped support sleeve 20 to define both an outer dorsal strip 23 and an outer palmar strip 27. More specifically, the outer dorsal strip 23 is defined by the stretchable radius panel 14 and an adjacent outer edge of the U-shaped support sleeve 20, and the outer palmar strip 27 is defined by the stretchable radius panel 14 and an adjacent outer edge of the U-shaped support sleeve 20.

An oblique palmar-tensioning strap 16 extends from the distal end of the U-shaped support sleeve's palmar section 26. The oblique palmar-tensioning strap 16 is positioned between the patient's thumb and forefinger (i.e., near the thenar space) and then securely and releasably affixed to the U-shaped support sleeve's dorsal section 22 (e.g., via hook-and-loop fasteners, such as VELCRO-brand fasteners). The oblique palmar-tensioning strap 16 helps to position and secure the wrist brace 10 to the patient's wrist and forearm. An optional palmar pad 18, which is positioned at the transition between the U-shaped support sleeve's palmar section 26 and the oblique palmar-tensioning strap 16, provides the patient with enhanced comfort and support.

The U-shaped support sleeve 20 can include stabilizing members to limit flexion and extension. In the exemplary wrist-brace embodiments depicted in FIGS. 1-4 and FIGS. 5-6, a longitudinal stiffening dorsal stay 28 is internally secured within the U-shaped support sleeve's dorsal section 22, and a longitudinal stiffening palmar stay 29 is internally secured within the U-shaped support sleeve's palmar section 26. As shown in FIGS. 2-3, the palmar stay 29 conforms to the shape of the patient's forearm, wrist, and palm. In addition, a longitudinal ulnar stay (not shown) can be internally secured within the U-shaped support sleeve's ulnar section 24. Including stays on two or more sides of the wrist brace (e.g., a wrist brace having a dorsal stay, a palmar stay, and an ulnar stay) protects against impact forces and helps reduce the likelihood of reinjuring the patient's wrist and hand.

The stabilizing members (i.e., stays) may be formed from metals, alloys, plastics, or other materials providing sufficient rigidity to resist movement and retain a desired shape while maintaining adequate adjustability for wear on the forearm, wrist, and hand. Typically, the stabilizing members are made of aluminum. In some embodiments, the stabilizing members can be manually adjusted to conform to the shape of the patient's forearm, wrist, and/or palm. Adjustable stabilizing members are sufficiently rigid to resist movement of the U-shaped support sleeve's distal end relative to the U-shaped support sleeve's proximal end and are sufficiently strong to provide protection against forces acting against the wrist brace (e.g., impact forces). The stabilizing members (i.e., stays) may be permanently secured within the wrist brace (e.g., an internally secured, permanent stay) or may be positioned within pockets formed in the U-shaped support sleeve to facilitate placement and removal of the stays (e.g., an internally secured, removable stay). Alternatively, the stabilizing members might be externally secured to the U-shaped support sleeve.

Dorsal eyelets 33 (or similar openings, such as reinforced holes and/or slots, or other dorsal lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) are formed through or otherwise positioned at or near (e.g., positioned upon) the U-shaped support sleeve's dorsal section 22 (e.g., at the outer dorsal strip 23). Similarly, palmar eyelets 37 (or similar openings, such as reinforced holes and/or slots, or other palmar lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) are formed through or otherwise positioned at or near (e.g., positioned upon) the U-shaped support sleeve's palmar section 26 (e.g., at the outer palmar strip 27). The shorter exemplary wrist brace 10 depicted in FIGS. 1-4 includes four dorsal eyelets 33 a, 33 c, 33 f, 33 h and two palmar eyelets 37 d, 37 e (i.e., imbalanced eyelets on either side of the U-shaped support sleeve 20). The longer exemplary wrist brace 10′ depicted in FIGS. 5-6 includes six dorsal eyelets 33 a, 33 c, 33 f, 33 h, 33 k, 33 n and four palmar eyelets 37 d, 37 e, 37 i, 37 j (i.e., imbalanced eyelets on either side of the U-shaped support sleeve 20). Those having ordinary skill in the art will understand that exemplary wrist braces according to the present invention may employ any lace-redirection mechanisms (e.g., reinforced openings, or external loops, hooks, folded webbing, and/or buckles) in addition to or instead of eyelets.

Moreover, it is within the scope of the present wrist-brace invention to include one or more external flaps (not shown) on the exterior of the U-shaped support sleeve to facilitate redirection of a lace. In one wrist-brace embodiment, a dorsal flap having eyelets or other lace-redirection mechanisms can be positioned upon the U-shaped support sleeve's dorsal section (e.g., near the stretchable radius panel), and the lace may be guided through the dorsal flap's lace-redirection mechanisms (e.g., eyelets) and the palmar eyelets (or other lace-redirection mechanisms) to promote even closure of the closed wrist-brace sleeve and to achieve cast-like compression on a patient's forearm, wrist, and hand. In another wrist-brace embodiment, a palmar flap having eyelets or other lace-redirection mechanisms can be positioned upon the U-shaped support sleeve's palmar section (e.g., near the stretchable radius panel), and the lace may be guided through the palmar flap's lace-redirection mechanisms (e.g., eyelets) and the dorsal eyelets (or other lace-redirection mechanisms) to promote even closure of the closed wrist-brace sleeve and to achieve cast-like compression on a patient's forearm, wrist, and hand. In yet another wrist-brace embodiment, a lace may be guided through both (i) a dorsal flap having eyelets or other lace-redirection mechanisms and (ii) a palmar flap having eyelets or other lace-redirection mechanisms to achieve cast-like compression on a patient's forearm, wrist, and hand, thereby restricting flexion, extension, and lateral movement of the wrist joint.

The shorter exemplary wrist brace 10 depicted in FIGS. 1-4 includes a lacing closure tab 30 through which one or more closure-tab eyelets 31 are formed. The longer exemplary wrist brace 10′ depicted in FIGS. 5-6 includes multiple lacing closure tabs 30′ and 30″ through which one or more closure-tab eyelets 31 are formed. More generally, closure-tab eyelets 31 (or similar openings, such as reinforced holes and/or slots, or other closure-tab lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) may be formed through or otherwise positioned at or near (e.g., positioned upon) the lacing closure tab(s) 30.

Each lacing closure tab 30 includes a mechanism, such as a hook-and-loop fastener, to releasably secure the lacing closure tab 30 to another part of the wrist brace 10. In the shorter exemplary wrist-brace embodiment depicted in FIG. 3, two closure-tab eyelets 31 b, 31 g are formed through or otherwise positioned upon the lacing closure tab 30. In the longer exemplary wrist-brace embodiment depicted in FIG. 5, one closure-tab eyelet 31 b is formed through or otherwise positioned upon the proximal lacing closure tab 30′ and two closure-tab eyelets 31 g, 31 m are formed through or otherwise positioned upon the distal lacing closure tab 30″. The closure-tab eyelets 31 help to ensure that each lacing closure tab 30 remains centered on the U-shaped support sleeve 20 as the lacing closure tab 30 is pulled over and around the closed wrist-brace sleeve 12.

A lace 40 is freely threaded (or otherwise interlaced) though the respective dorsal eyelets 33, palmar eyelets 37, and closure-tab eyelets 31. The lace 40, which typically resists excessive stretching, can move freely to accommodate the typical non-cylindrical anatomy of a patient's forearm in which the arm tapers from the elbow to the wrist (e.g., a frustoconical shape). This free movement of the lace 40 facilitates consistent tension along the lace 40. This even tension is transferred to the respective dorsal eyelets 33, palmar eyelets 37, and closure-tab eyelets 31 through which the lace 40 is interlaced.

Each lacing closure tab 30 is moveably connected to the lace 40. When the lacing closure tab 30 is not releasably secured to another part of the wrist brace (e.g., releasably affixed to the closed wrist-brace sleeve 12), the lacing closure tab 30 can move substantially freely along the lace 40. The shorter exemplary wrist brace 10 depicted in FIGS. 1-4 does not fixedly attach the one lace 40 to the lacing closure tab 30, either fully or partially. Similarly, the longer exemplary wrist brace 10′ depicted in FIGS. 5-6 does not fixedly attach the one lace 40 to the respective closure tabs 30′ and 30″, either fully or partially. Rather, in these exemplary wrist-brace embodiments, the lace 40 may pass substantially freely through each of the closure-tab eyelets 31. As depicted in FIGS. 1-6, each strand of lace 40 from a dorsal eyelet 33 to a closure tab 30 is freely threaded through a closure-tab eyelet 31. This “free-floating” closure-tab design enables the patient to readily equilibrate lace tension through the various eyelets (i.e., the dorsal eyelets 33 and palmar eyelets 37) positioned along the length of the wrist brace in a way that applies substantially consistent compression to the patient's forearm and wrist. The lace 40 and each moveably attached lacing closure tab 30 wrap circumferentially around—rather than helically along—the patient's forearm in a way that uniformly closes and tensions the closed wrist-brace sleeve 12.

Typically, one lace 40 has (i) a first end fixed to the U-shaped support sleeve's interior surface at the U-shaped support sleeve's proximal end (e.g., secured at either the proximal end of the outer palmar strip 27 or the proximal end of the outer dorsal strip 23) and (ii) a second end fixed to the U-shaped support sleeve's interior surface at the U-shaped support sleeve's distal end (e.g., secured at either the distal end of the outer palmar strip 27 or the distal end of the outer dorsal strip 23). In this embodiment, either the dorsal eyelets 33 or the palmar eyelets 37 are positioned between the lace's first fixed end and the lace's second fixed end.

As illustrated in FIGS. 1-4 in which the ends of lace 40 are fixed to the outer palmar strip 27, pulling the lacing closure tab 30 away from the U-shaped support sleeve's dorsal section 22 (and over and around the U-shaped support sleeve's palmar section 26) uniformly closes and tensions the closed wrist-brace sleeve 12 by drawing together the U-shaped support sleeve's dorsal section 22 and the U-shaped support sleeve's palmar section 26. Similarly, in an alternative wrist-brace embodiment (not shown) in which the ends of lace 40 are fixed to the outer dorsal strip 27, pulling the lacing closure tab away from the U-shaped support sleeve's palmar section 26 (and over and around the U-shaped support sleeve's dorsal section 22) uniformly closes and tensions the closed wrist-brace sleeve 12 by drawing together the U-shaped support sleeve's palmar section 26 and the U-shaped support sleeve's dorsal section 22. These same considerations apply to wrist-brace embodiments that include multiple lacing closure tabs, such as the proximal lacing closure tab 30′ and the distal lacing closure tab 30″ illustrated in FIGS. 5-6.

In the shorter exemplary wrist-brace embodiment depicted in FIG. 3, a single lace 40 has (i) a first proximal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's proximal end (i.e., a proximal fixation 41 p toward the proximal end of the outer palmar strip 27) and (ii) a second distal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's distal end (i.e., a distal fixation 41 d toward the distal end of the outer palmar strip 27). In the exemplary wrist-brace embodiment depicted in FIG. 3, two palmar eyelets 37 d, 37 e are formed along outer palmar strip 27 between the lace's proximal fixation 41 p and the lace's distal fixation 41 d, and four dorsal eyelets 33 a, 33 c, 33 f, 37 h are formed along the outer dorsal strip 23.

As illustrated in the exemplary wrist-brace embodiment depicted in FIG. 3, the wrist brace 10 includes a compression-enhancing lacing configuration that readily equilibrates (e.g., simultaneously evens) the tension in the lace 40 as the lacing closure tab 30 is extended from the closed wrist-brace sleeve 12. From the proximal end of the wrist brace 10 to the distal end of the wrist brace 10, the lace 40 passes from its proximal fixation 41 p to and through an outer proximal dorsal eyelet 33 a, to and through a proximal closure-tab eyelet 31 b, to and through an inner proximal dorsal eyelet 33 c, to and through a proximal palmar eyelet 37 d. The lace 40 then passes lengthwise along the interior surface of the outer palmar strip 27 from the proximal palmar eyelet 37 d to and through a distal palmar eyelet 37 e so that, between the proximal palmar eyelet 37 d and the distal palmar eyelet 37 e, the lace 40 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 20. The lace 40 then passes from the distal palmar eyelet 37 e to and through an inner distal dorsal eyelet 33 f, to and through a distal closure-tab eyelet 31 g, to and through an outer distal dorsal eyelet 33 h, and to the distal fixation 41 d.

In the longer exemplary wrist-brace embodiment depicted in FIG. 5, a single lace 40 has (i) a first proximal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's proximal end (i.e., a proximal fixation 41 p toward the proximal end of the outer palmar strip 27) and (ii) a second distal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's distal end (i.e., a distal fixation 41 d toward the distal end of the outer palmar strip 27). In the exemplary wrist-brace embodiment depicted in FIG. 5, four palmar eyelets 37 d, 37 e, 37 i, 37 j are formed along outer palmar strip 27 between the lace's proximal fixation 41 p and the lace's distal fixation 41 d, and six dorsal eyelets 33 a, 33 c, 33 f, 33 h, 33 k, 33 n are formed along the outer dorsal strip 23.

As illustrated in the exemplary wrist-brace embodiment depicted in FIG. 5, the wrist brace 10′ includes a compression-enhancing lacing configuration that readily equilibrates the tension in the lace 40 as the lacing closure tabs 30′, 30″ are extended from the closed wrist-brace sleeve 12. From the proximal end of the wrist brace 10′ to the distal end of the wrist brace 10′, the lace 40 passes from its proximal fixation 41 p to and through an outermost proximal dorsal eyelet 33 a, to and through a closure-tab eyelet 31 b formed in the proximal lacing closure tab 30′, to and through a central proximal dorsal eyelet 33 c, to and through an outer proximal palmar eyelet 37 d. The lace 40 then passes lengthwise along the interior surface of the outer palmar strip 27 from the outer proximal palmar eyelet 37 d to and through an inner proximal palmar eyelet 37 e so that, between the outer proximal palmar eyelet 37 d and the inner proximal palmar eyelet 37 e, the lace 40 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 20. The lace 40 then passes from the inner proximal palmar eyelet 37 e to and through an inner proximal dorsal eyelet 33 f, to and through a first distal closure-tab eyelet 31 g formed in the distal lacing closure tab 30″, to and through an inner distal dorsal eyelet 33 h, to and through an inner distal palmar eyelet 37 i. The lace 40 then passes lengthwise along the interior surface of the outer palmar strip 27 from the inner distal palmar eyelet 37 i to and through an outer distal palmar eyelet 37 j so that, between the inner distal palmar eyelet 37 i and the outer distal palmar eyelet 37 j, the lace 40 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 20. The lace 40 then passes from the outer distal palmar eyelet 37 j to and through a central distal dorsal eyelet 33 k, to and through a second distal closure-tab eyelet 31 m formed in the distal lacing closure tab 30″, to and through an outermost distal dorsal eyelet 33 n, and to the distal fixation 41 d.

Optionally, the lace 40 passes through one or more lacing channels 42, which may be secured to or otherwise formed in the stretchable radius panel 14. In the shorter exemplary wrist-brace embodiment depicted in FIG. 3, the lace 40 passes through one lacing channel 42 secured to the stretchable radius panel 14 as the lace 40 passes from the outer distal dorsal eyelet 33 h to the distal fixation 41 d. In the longer exemplary wrist-brace embodiment depicted in FIG. 5, the lace 40 passes through one lacing channel 42 secured to the stretchable radius panel 14 as the lace 40 passes from the outermost distal dorsal eyelet 33 n to the distal fixation 41 d. As will be appreciated by those having ordinary skill in the art, each lacing channel 42 should be positioned to facilitate passage of the lace 40 between the outer palmar strip 27 and the outer dorsal strip 23. For example, positioning lacing channel(s) 42 at either the distal end or the proximal end of the stretchable radius panel 14, or both the distal end and the proximal end of the stretchable radius panel 14, helps to maintain the proper positioning of stretchable radius panel 14 against the patient's forearm as shown in FIG. 2. In practice, securing the lace 40 to the stretchable radius panel 14 via one or more lacing channels 42, typically at the distal end and/or proximal end of a cushioned, stretchable radius panel 14, reduces patient discomfort by preventing the lace 40 from migrating beyond the end of the stretchable radius panel 14 when the wrist brace 10 is compressively and securely applied to the patient's wrist and forearm.

As illustrated in the exemplary wrist-brace embodiments depicted in FIGS. 1-4 and FIGS. 5-6, hook-and-loop fasteners 45 are secured to the surfaces of the wrist brace 10 to facilitate closure of the wrist brace 10 to the patient's forearm, wrist, and hand. For example, loop-fasteners 46 (e.g., loop-fastener strips) can be secured to the outer surfaces of the U-shaped support sleeve 20, typically at the topside dorsal section 22, the ulnar section 24, and the underside palmar section 26. Hook-fasteners 47 are provided elsewhere on the wrist brace 10, such as on a surface of each lacing closure tab 30 and a surface at the end of the oblique palmar-tensioning strap 16.

As illustrated in FIGS. 1-4 and FIGS. 5-6, the patient may secure the wrist brace 10 to his forearm, wrist, and hand by pulling a lacing closure tab 30 perpendicularly away from the U-shaped support sleeve's dorsal section 22 and over and around the U-shaped support sleeve's palmar section 26. This evenly closes and tensions the closed wrist-brace sleeve 12 by drawing together the U-shaped support sleeve's dorsal section 22 and the U-shaped support sleeve's palmar section 26. Depending on the girth of the patient's forearm, the hook-fasteners 47 on a surface of the lacing closure tab 30 will engage one or more loop-fasteners 46 positioned upon the respective outer surfaces of the dorsal section 22, the ulnar section 24, and the palmar section 26. The hook-fastener 47 at the end of the oblique palmar-tensioning strap 16 can be releasably secured to the U-shaped support sleeve's dorsal section 22.

FIGS. 7-10 depict another exemplary wrist-brace embodiment sized for a patient. FIGS. 11-12 depict a similar, but longer, exemplary wrist-brace embodiment sized for a patient. Each of these wrist braces includes more substantial thumb support as compared with the wrist-brace embodiments depicted in FIGS. 1-6. As with the wrist-brace embodiments depicted in FIGS. 1-6, the wrist brace embodiments depicted in FIGS. 7-12 are configured for either a left forearm, wrist, and hand or a right forearm, wrist, and hand. Those having ordinary skill in the art will understand that a left-hand orientation is a mirror image of a right-hand orientation. FIGS. 7-12 illustrate a right-hand orientation. Appendix III includes photographs of an exemplary prototype of the wrist brace depicted in FIGS. 7-10, and Appendix IV includes photographs of an exemplary prototype of the longer wrist brace depicted in FIGS. 11-12.

The description of the shorter wrist-brace embodiment depicted in FIGS. 7-10 typically applies to the longer wrist-brace embodiment depicted in FIGS. 11-12, except as noted in the supporting description, figures, and photographs.

With reference to the exemplary wrist brace 110 depicted in FIGS. 7-10 (and, as noted, the related, longer exemplary wrist brace 110′ depicted in FIGS. 11-12), the wrist brace 110 includes a closed wrist-brace sleeve 112 defining an interior surface and an exterior surface. The closed wrist-brace sleeve 112 is formed by a stretchable ulnar panel 124 connected to a U-shaped support sleeve 120.

The U-shaped support sleeve 120 includes a topside dorsal section 122, a radius section 114, and an underside palmar section 126. The radius section 114, which is designed to extend to the base of a patient's thumb, is contiguously positioned between the dorsal section 122 and the palmar section 126 to define the U-shaped support sleeve 120. The topside dorsal section 122 is positioned opposite the underside palmar section 126, and the radius section 114 is positioned opposite the stretchable ulnar panel 124. Typically, the U-shaped support sleeve 120, which opens to a patient's forearm ulna, is substantially inelastic (e.g., formed from flexible, low-stretch material) to help stabilize the patient's wrist and hand.

The stretchable ulnar panel 124, which may be cushioned for the patient's comfort, is affixed to both the U-shaped support sleeve's dorsal section 122 and the U-shaped support sleeve's palmar section 126, thereby closing the gap in the U-shaped support sleeve 120 to form the closed wrist-brace sleeve 112. In addition, the stretchable ulnar panel 124 is typically positioned within the gap in the U-shaped support sleeve 120 to define both an outer dorsal strip 123 and an outer palmar strip 127. More specifically, the outer dorsal strip 123 is defined by the stretchable ulnar panel 124 and an adjacent outer edge of the U-shaped support sleeve 120, and the outer palmar strip 127 is defined by the stretchable ulnar panel 124 and an adjacent outer edge of the U-shaped support sleeve 120.

A thumb-tensioning strap 117 extends from the distal end of the U-shaped support sleeve's radius section 114. The thumb-tensioning strap 117 is positioned between the patient's thumb and forefinger, wrapped around the patient's thumb, and then securely and releasably affixed to the U-shaped support sleeve's radius section 114 (e.g., via hook-and-loop fasteners, such as VELCRO-brand fasteners). The thumb-tensioning strap 117 not only helps to position and secure the wrist brace 110 to the patient's wrist and forearm, but also helps to position and secure the support sleeve's radius section 114 against the base of the patient's thumb. Optional padding 118, which is positioned near the thumb-tensioning strap 117, such as upon the U-shaped support sleeve's palmar section 126 and/or the U-shaped support sleeve's radius section 114, provides the patient with enhanced comfort and support. More generally, padding may be applied to the interior surfaces of the closed wrist-brace sleeve 112 to help engage the patient's wrist and hand and to improve patient comfort.

The U-shaped support sleeve 120 can include stabilizing members to limit flexion and extension. In the exemplary wrist-brace embodiments depicted in FIGS. 7-10 and FIGS. 11-12, a longitudinal stiffening dorsal stay 128 is internally secured within the U-shaped support sleeve's dorsal section 122, a longitudinal stiffening radius stay 115 is internally secured within the U-shaped support sleeve's radius section 114, and a longitudinal stiffening palmar stay 129 is internally secured within the U-shaped support sleeve's palmar section 126. As shown in FIGS. 7-8, the radius stay 115 conforms to the shape of the patient's forearm, wrist, and thumb. As shown in FIG. 7, the palmar stay 129 conforms to the shape of the patient's forearm, wrist, and palm. Including stays on two or more sides of the wrist brace (e.g., a wrist brace having a dorsal stay, a radius stay, and a palmar stay,) protects against impact forces and helps reduce the likelihood of reinjuring the patient's wrist and hand.

Dorsal eyelets 133 (or similar openings, such as reinforced holes and/or slots, or other dorsal lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) are formed through or otherwise positioned at or near (e.g., positioned upon) the U-shaped support sleeve's dorsal section 122 (e.g., at the outer dorsal strip 123). Similarly, palmar eyelets 137 (or similar openings, such as reinforced holes and/or slots, or other palmar lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) are formed through or otherwise positioned at or near (e.g., positioned upon) the U-shaped support sleeve's palmar section 126 (e.g., at the outer palmar strip 127). The shorter exemplary wrist brace 110 depicted in FIGS. 7-10 includes four dorsal eyelets 133 a, 133 c, 133 f, 133 h and two palmar eyelets 137 d, 137 e (i.e., imbalanced eyelets on either side of the U-shaped support sleeve 120). The longer exemplary wrist brace 110′ depicted in FIGS. 11-12 includes six dorsal eyelets 133 a, 133 c, 133 f, 133 h, 133 k, 133 n and four palmar eyelets 137 d, 137 e, 137 i, 137 j (i.e., imbalanced eyelets on either side of the U-shaped support sleeve 120). Those having ordinary skill in the art will understand that exemplary wrist braces according to the present invention may employ any lace-redirection mechanisms (e.g., reinforced holes and slots, or external loops, hooks, folded webbing, and/or buckles) in addition to or instead of eyelets.

As noted, it is within the scope of the present wrist-brace invention to include one or more external flaps (not shown) on the exterior of the U-shaped support sleeve to facilitate redirection of the lace. In one wrist-brace embodiment, a dorsal flap having eyelets or other lace-redirection mechanisms can be positioned upon the U-shaped support sleeve's dorsal section (e.g., near the stretchable ulnar panel), and the lace may be guided through the dorsal flap's lace-redirection mechanisms (e.g., eyelets) and the palmar eyelets (or other lace-redirection mechanisms) to promote even closure of the closed wrist-brace sleeve and to achieve cast-like compression on a patient's forearm, wrist, and hand. In another wrist-brace embodiment, a palmar flap having eyelets or other lace-redirection mechanisms can be positioned upon the U-shaped support sleeve's palmar section (e.g., near the stretchable ulnar panel), and the lace may be guided through the palmar flap's lace-redirection mechanisms (e.g., eyelets) and the dorsal eyelets (or other lace-redirection mechanisms) to promote even closure of the closed wrist-brace sleeve and to achieve cast-like compression on a patient's forearm, wrist, and hand. In yet another wrist-brace embodiment, a lace may be guided through both (i) a dorsal flap having eyelets or other lace-redirection mechanisms and (ii) a palmar flap having eyelets or other lace-redirection mechanisms to achieve cast-like compression on a patient's forearm, wrist, and hand, thereby restricting flexion, extension, and lateral movement of the wrist joint.

The shorter exemplary wrist brace 110 depicted in FIGS. 7-10 includes a lacing closure tab 130 through which one or more closure-tab eyelets 131 are formed. The longer exemplary wrist brace 110′ depicted in FIGS. 11-12 includes multiple lacing closure tabs 130′ and 130″ through which one or more closure-tab eyelets 131 are formed. More generally, closure-tab eyelets 131 (or similar openings, such as reinforced holes and/or slots, or other closure-tab lace-redirection mechanisms, such as loops, hooks, folded webbing, and/or buckles) may be formed through or otherwise positioned at or near (e.g., positioned upon) the lacing closure tab(s) 130.

Each lacing closure tab 130 includes a mechanism, such as a hook-and-loop fastener, to releasably secure the lacing closure tab 130 to another part of the wrist brace 110. In the shorter exemplary wrist-brace embodiment depicted in FIG. 9, two closure-tab eyelets 131 b, 131 g are formed through or otherwise positioned upon the lacing closure tab 130. In the longer exemplary wrist-brace embodiment depicted in FIG. 11, one closure-tab eyelet 131 b is formed through or otherwise positioned upon the proximal lacing closure tab 130′ and two closure-tab eyelets 131 g, 131 m are formed through or otherwise positioned upon the distal lacing closure tab 130″. The closure-tab eyelets 131 help to ensure that each lacing closure tab 130 remains centered on the U-shaped support sleeve 120 as the lacing closure tab 130 is pulled over and around the closed wrist-brace sleeve 112.

A lace 140 is freely threaded (or otherwise interlaced) though the respective dorsal eyelets 133, palmar eyelets 137, and closure-tab eyelets 131. The lace 140 can move freely to accommodate the typical non-cylindrical anatomy of a patient's forearm in which the arm tapers from the elbow to the wrist (e.g., a frustoconical shape). This free movement of the lace 140 facilitates consistent tension along the lace 140. This even tension is transferred to the respective dorsal eyelets 133, palmar eyelets 137, and closure-tab eyelets 131 through which the lace 140 is interlaced.

Each lacing closure tab 130 is moveably connected to the lace 140. When the lacing closure tab 130 is not releasably secured to another part of the wrist brace (e.g., releasably affixed to the closed wrist-brace sleeve 112), the lacing closure tab 130 can move substantially freely along the lace 140. The shorter exemplary wrist brace 110 depicted in FIGS. 7-10 does not fixedly attach the one lace 140 to the lacing closure tab 130, either fully or partially. Similarly, the longer exemplary wrist brace 110′ depicted in FIGS. 11-12 does not fixedly attach the one lace 140 to the respective closure tabs 130′ and 130″, either fully or partially. Rather, in these exemplary wrist-brace embodiments, the lace 140 may pass substantially freely through each of the closure-tab eyelets 131. As depicted in FIGS. 7-12, each strand of lace 140 from a dorsal eyelet 133 to a closure tab 130 is freely threaded through a closure-tab eyelet 131. This “free-floating” closure-tab design enables the patient to readily equilibrate lace tension through the various eyelets (i.e., the dorsal eyelets 133 and palmar eyelets 137) positioned along the length of the wrist brace in a way that applies substantially consistent compression to the patient's forearm and wrist. The lace 140 and each moveably attached lacing closure tab 130 wrap circumferentially around—rather than helically along—the patient's forearm in a way that uniformly closes and tensions the closed wrist-brace sleeve 112.

Typically, one lace 140 has (i) a first end fixed to the U-shaped support sleeve's interior surface at the U-shaped support sleeve's proximal end (e.g., secured at either the proximal end of the outer palmar strip 127 or the proximal end of the outer dorsal strip 123) and (ii) a second end fixed to the U-shaped support sleeve's interior surface at the U-shaped support sleeve's distal end (e.g., secured at either the distal end of the outer palmar strip 127 or the distal end of the outer dorsal strip 123). In this embodiment, either the dorsal eyelets 133 or the palmar eyelets 137 are positioned between the lace's first fixed end and the lace's second fixed end.

As illustrated in FIGS. 7-10 in which the ends of lace 140 are fixed to the outer palmar strip 127, pulling the lacing closure tab 130 away from the U-shaped support sleeve's dorsal section 122 (and over and around the U-shaped support sleeve's palmar section 126) uniformly closes and tensions the closed wrist-brace sleeve 112 by drawing together the U-shaped support sleeve's dorsal section 122 and the U-shaped support sleeve's palmar section 126. Similarly, in an alternative wrist-brace embodiment in which the ends of lace 40 are fixed to the outer dorsal strip 123, pulling the lacing closure tab away from the U-shaped support sleeve's palmar section 126 (and over and around the U-shaped support sleeve's dorsal section 122) uniformly closes and tensions the closed wrist-brace sleeve 112 by drawing together the U-shaped support sleeve's palmar section 126 and the U-shaped support sleeve's dorsal section 122. These same considerations apply to wrist-brace embodiments that include multiple lacing closure tabs, such as the proximal lacing closure tab 130′ and the distal lacing closure tab 130″ illustrated in FIGS. 11-12.

In the shorter exemplary wrist-brace embodiment depicted in FIG. 9, a single lace 140 has (i) a first proximal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's proximal end (i.e., a proximal fixation 141 p toward the proximal end of the outer palmar strip 127) and (ii) a second distal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's distal end (i.e., a distal fixation 141 d toward the distal end of the outer palmar strip 127). In the exemplary wrist-brace embodiment depicted in FIG. 9, two palmar eyelets 137 d, 137 e are formed along outer palmar strip 127 between the lace's proximal fixation 141 p and the lace's distal fixation 141 d, and four dorsal eyelets 133 a, 133 c, 133 f, 137 h are formed along the outer dorsal strip 123.

As illustrated in the exemplary wrist-brace embodiment depicted in FIG. 9, the wrist brace 110 includes a compression-enhancing lacing configuration that readily equilibrates (e.g., simultaneously evens) the tension in the lace 140 as the lacing closure tab 130 is extended from the closed wrist-brace sleeve 112. From the proximal end of the wrist brace 110 to the distal end of the wrist brace 110, the lace 140 passes from its proximal fixation 141 p to and through an outer proximal dorsal eyelet 133 a, to and through a proximal closure-tab eyelet 131 b, to and through an inner proximal dorsal eyelet 133 c, to and through a proximal palmar eyelet 137 d. The lace 140 then passes lengthwise along the interior surface of the outer palmar strip 127 from the proximal palmar eyelet 137 d to and through a distal palmar eyelet 137 e so that, between the proximal palmar eyelet 137 d and the distal palmar eyelet 137 e, the lace 140 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 120. The lace 140 then passes from the distal palmar eyelet 137 e to and through an inner distal dorsal eyelet 133 f, to and through a distal closure-tab eyelet 131 g, to and through an outer distal dorsal eyelet 133 h, and to the distal fixation 141 d.

In the longer exemplary wrist-brace embodiment depicted in FIG. 11, a single lace 140 has (i) a first proximal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's proximal end (i.e., a proximal fixation 141 p toward the proximal end of the outer palmar strip 127) and (ii) a second distal end fixed to the U-shaped support sleeve's interior surface nearer the U-shaped support sleeve's distal end (i.e., a distal fixation 141 d toward the distal end of the outer palmar strip 127). In the exemplary wrist-brace embodiment depicted in FIG. 11, four palmar eyelets 137 d, 137 e, 137 i, 137 j are formed along outer palmar strip 127 between the lace's proximal fixation 141 p and the lace's distal fixation 141 d, and six dorsal eyelets 133 a, 133 c, 133 f, 133 h, 133 k, 133 n are formed along the outer dorsal strip 123.

As illustrated in the exemplary wrist-brace embodiment depicted in FIG. 11, the wrist brace 110′ includes a compression-enhancing lacing configuration that readily equilibrates the tension in the lace 140 as the lacing closure tabs 130′, 130″ are extended from the closed wrist-brace sleeve 112. From the proximal end of the wrist brace 110′ to the distal end of the wrist brace 110′, the lace 140 passes from its proximal fixation 141 p to and through an outermost proximal dorsal eyelet 133 a, to and through a closure-tab eyelet 131 b formed in the proximal lacing closure tab 130′, to and through a central proximal dorsal eyelet 133 c, to and through an outer proximal palmar eyelet 137 d. The lace 140 then passes lengthwise along the interior surface of the outer palmar strip 127 from the outer proximal palmar eyelet 137 d to and through an inner proximal palmar eyelet 137 e so that, between the outer proximal palmar eyelet 137 d and the inner proximal palmar eyelet 137 e, the lace 140 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 120. The lace 140 then passes from the inner proximal palmar eyelet 137 e to and through an inner proximal dorsal eyelet 133 f, to and through a first distal closure-tab eyelet 131 g formed in the distal lacing closure tab 130″, to and through an inner distal dorsal eyelet 133 h, to and through an inner distal palmar eyelet 137 i. The lace 140 then passes lengthwise along the interior surface of the outer palmar strip 127 from the inner distal palmar eyelet 137 i to and through an outer distal palmar eyelet 137 j so that, between the inner distal palmar eyelet 137 i and the outer distal palmar eyelet 137 j, the lace 140 is substantially parallel to the adjacent outer edge of the U-shaped support sleeve 120. The lace 140 then passes from the outer distal palmar eyelet 137 j to and through a central distal dorsal eyelet 133 k, to and through a second distal closure-tab eyelet 131 m formed in the distal lacing closure tab 130″, to and through an outermost distal dorsal eyelet 133 n, and to the distal fixation 141 d.

Optionally, the lace 140 passes through one or more lacing channels 142, which may be secured to or otherwise formed in the stretchable ulnar panel 124. In the shorter exemplary wrist-brace embodiment depicted in FIG. 9, the lace 140 passes through one lacing channel 142 secured to the stretchable ulnar panel 124 as the lace 140 passes from the outer distal dorsal eyelet 133 h to the distal fixation 141 d. In the longer exemplary wrist-brace embodiment depicted in FIG. 11, the lace 140 passes through one lacing channel 142 secured to the stretchable ulnar panel 124 as the lace 140 passes from the outermost distal dorsal eyelet 133 n to the distal fixation 141 d. As will be appreciated by those having ordinary skill in the art, each lacing channel 142 should be positioned to facilitate passage of the lace 140 between the outer palmar strip 127 and the outer dorsal strip 123. For example, positioning lacing channel(s) 142 at either the distal end or the proximal end of the stretchable ulnar panel 124, or both the distal end and the proximal end of the stretchable ulnar panel 124, helps to maintain the proper positioning of stretchable ulnar panel 124 against the patient's forearm as shown in FIG. 8. In practice, securing the lace 140 to the stretchable ulnar panel 124 via one or more lacing channels 142, typically at the distal end and/or proximal end of a cushioned, stretchable ulnar panel 124, reduces patient discomfort by preventing the lace 140 from migrating beyond the end of the stretchable ulnar panel 124 when the wrist brace 110 is compressively and securely applied to the patient's wrist and forearm.

As illustrated in the exemplary wrist-brace embodiments depicted in FIGS. 7-10 and FIGS. 11-12, hook-and-loop fasteners 145 are secured to the surfaces of the wrist brace 110 to facilitate closure of the wrist brace 110 to the patient's forearm, wrist, and hand. For example, loop-fasteners 146 (e.g., loop-fastener strips) can be secured to the outer surfaces of the U-shaped support sleeve 120, typically at the topside dorsal section 122, the radius section 114, and the underside palmar section 126. Hook-fasteners 147 are provided elsewhere on the wrist brace 110, such as on a surface of each lacing closure tab 130 and a surface at the end of the thumb-tensioning strap 117.

As illustrated in FIGS. 7-10 and FIGS. 11-12, the patient may secure the wrist brace 110 to his forearm, wrist, and hand by pulling a lacing closure tab 130 perpendicularly away from the U-shaped support sleeve's dorsal section 122 and over and around the U-shaped support sleeve's palmar section 126. This evenly closes and tensions the closed wrist-brace sleeve 112 by drawing together the U-shaped support sleeve's dorsal section 122 and the U-shaped support sleeve's palmar section 126. Depending on the girth of the patient's forearm, the hook-fasteners 147 on a surface of the lacing closure tab 130 will engage one or more loop-fasteners 146 positioned upon the respective outer surfaces of the dorsal section 122, the radius section 114, and the palmar section 126. The hook-fastener 147 at the end of the thumb-tensioning strap 117 can be releasably secured to either the U-shaped support sleeve's radius section 114 or U-shaped support sleeve's palmar section 126.
